Our Thoughts
Both the Diono Radian 3RXT Safe+ and the Nuna Revv are robust convertible car seats designed with safety as a paramount concern. While their price points are on the higher end of the spectrum, the unique features and long lifespan of each seat offer justification for the investment, especially for families who plan to use the seat for more than one child.
The Diono Radian 3RXT Safe+ is particularly attractive for families with multiple children, as its slim design allows for fitting three seats across in most vehicles. Its standout feature is the steel-reinforced frame which provides robust protection in the event of a collision. Colossal praises go to its weight limit in various configurations, allowing for longer use. For instance, in the rear-facing position, it supports up to 50 lbs, compared to the 40 lbs limit of the Nuna Revv. This means a child can stay in the safer rear-facing position for longer. Additionally, it has the advantage of being FAA approved for both forward and rear-facing modes, making it a more versatile travel companion compared to the Nuna Revv, which isn’t FAA approved.
On the other hand, the Nuna Revv brings innovation to the table with its unique 360° swiveling feature, vastly simplifying child loading especially in the rear-facing position. The seat rotation saves parents from awkwardly maneuvering their child into the car seat, reducing potential injuries such as back strain. It's an excellent choice for parents who prioritize convenience, aesthetics, and who have smaller cars due to its smaller width. Keep in mind, though, its 40 lbs weight limit might require parents to upgrade to a different seat sooner than with the Diono Radian 3RXT Safe+.
When deciding between these two solid car seats, it boils down to your key considerations. If you prioritize safety features, maximum weight limits for longer usage, or frequent travel, I would recommend the Diono Radian 3RXT Safe+. However, if you esteem innovation and convenience over all else, the rotating function of the Nuna Revv makes it a worthwhile investment. It's a high-end solution that addresses the hassle of placing children in and getting them out of the car seat, especially in the often challenging rear-facing position.
